ATQMIZER 0R VO-LATILIZER.

Specification of Letters Patent.

Application filed June 7, 1909. Serial No. 500,610.

To all whom it may concern:

Be it known that we, GEORGE H. GOLD- SMITH and JAMES C. RANKINE, citizens of the United States, residing, respectively, at- Saylesville and Pawtucket, in the county of Providence and State of Rhode Island, have invented a new and useful Improvement in Atomizers or Volatilizers, of which the following is a specification.

This invention relates to atomizers or vola'tilizers, and has particular reference to an atomizer in which currents of air are centrifugally set up by a plurality of rotary members.

The object of this invention is to construct an atomizing machine which will thoroughly and efliciently separate a liquid into minute particles or spray and cast it off into the atmosphere with a force which will cause it to intimately co-mix with'the air.

Generally speaking our invention contemplates the use of pairs of disks concentrically mounted so as who revoluble together or in a variety of relations differing as 'regards speed and direction. We have found that disks mounted as herein designed, and provided on their peripheral edges with serrations or teeth turned out of the plane of the disk, when revolved, each set up a current of air, which currents are united and form a powerful factor for the distribution of divided liquids. In addition to the currents thus peripherally set up however, there are further radial .air currents set up between the concentric opposing disks, which drift to the outer edges of the disksor fans as we design to call them, and crossing the peripheral currents above mentioned, are united therewith. The action of these counter currents gives a further separating power to the air and the liquid to be disseminated is still more finely and thoroughly divided and distributed.

Bymounting the pairs of disks for independent rotation, the relative value of each current, namely the two peripheral currents set up by the disks or fans and the radial or centrifugal currents set up between said fans, can be .regulated. That is, the fans may be run at varying speeds, or the same speed, in the sameor in opposite directions,

. whereby the currentsmay be caused to combine and cooperate, or may be caused to oppose one another to regulate the forms of nebulization of the device.

I tween the elements.

In this specification, reference is had to the accompanying drawings, which form a part thereof and in which,

Figure 1 is an elevation of our device,

shown as suspended from a ceiling or other suitable support. Fig. 2 is a sectional elevation of the device, and Fig. 3 is a partial detail view of one of the fans or disks.

Referring in detail to said drawings, 1 is a suspension bracket havin arms which are secured to a ceiling or 0t er suitable overhead support and radiate from a heavy boxing or casing 2. Said casing 2is centrally bored at 3 to receive a vertical hollow fixed shaft 4, which is suspended thereby and depends more than half its length below said casing. Said shaft 4 is threaded at its ends to receive the lock-members or nuts 5 and 6, and the member 7. Member 7 is threaded on the upper endof said shaft and bears against the upper end of the casing 2, where it is locked by means of nut 6. Lock nut 5 is threaded on the intermediate por-. tion of said shaft, and locks the shaft in position at the lower end of the casing. The

lower end of said shaft 4 terminates in a sleeve or casing 11. At its lower end, said a sleeve 11 is flared to seat upon said foot 8 and is externally threaded to receive a cap 12. Said cap is centrally bored and threaded to receive the lower end of said shaft 9, a lock nut 13 insuring a rigid connection,'be-

Sleeve 11 is provided' with an annular flange 14, which is' of sufficient width to form a hearing or seat for a disk or circular fan 15, hereinafter described. Above said flange 14 theshell of the sleeve 11 is increased in thickness as at' 11 and bored to form an annular channel 16 and passages to permit'a flow of water from the top of said sleeve to the flange 1 1 and fan 15.

The lowerend of the portion 11' is out-- wardly flared at 17 to form a beari foot for a second revoluble sleeve 18, whlch is also flanged annularly at its lower end to form a seat or securing means for a fan 19 similar to fan 15. The upper end of each of sleeves 11 and 18 is provided with pulleys 20 and 21, whereby said sleeves and consequently said fans 15 and 19 maybe revolved at various speeds and in different directions at will. The interior of fixed shaft 4 is utilized as an oil reservoir, and feeds a lubricant to the bearings of sleeve 11 through ducts 22 a formed in said shaft 4. Sleeve 18 is provided with oil ducts 23, through which a lubricant may be fed into the annular channel 24 and thence to the bearing foot 17.

The aforesaid fans 15 and 19 comprise circular disks (Fig. 3) which are slightly dished and are provided with or formed into serrations or teeth 25-at their peripheral edges. Said teeth are or may be turned out of the plane of the disk, as indicated in Fig. 1." This twist or turn of said teeth depends upon the result desired or more advantageously sought. Each disk is also provided with a series of apertures 26, whose purpose is to intercept and distribute therethrough the centrifugal current set up when the disks or fans are revolved.

The member 7, which is seated on the casing 2, is externally threaded to receive the corresponding threads of a housing 27,

which is substantially dome-shaped and is provided at its upper end with an inlet opening 28. Said inlet is continued inwardly to form a depending valve-seat 29,

which is located centrally over the revoluble shaft 9 and is adapted to be closed by a valve 30 carried on the upper end of said shaft. Said valve 30 is mounted to revolve with said shaft 9 but is slidable'vertically on a squared portion 31 formed thereon.

The inlet 28 is connected to a suitable supply pipe 32 which furnishes water or any other desired fluid to the housing 27. Said housing is divided into two chambers by a partition '33, which extends across the housing for the greater part of the distance and then is turned vertically downward to pervmit a passage to a channel 34: formed through the member 7 and casing 52. Said passage is provided at its lower end with a nozzle 35 which furnishes the fluid to the channel 16 to feed the fans 15 and 19. The second chamber formed by partition 33 is separated from the member ,7 and lock nut 6 by a disk or plate 37, which forms with said partition 33 a governor and lubricating chamber 38. An oi1-inlet39 is furnished through which chamber 38 is supplied. A centrifugal governor 40 of suitable form is mounted on shaft 9, its lower arms being fixed and its upper arms slidably inclosing shaft 9 and bearing against the slidable valve 30. As shaft 9 is revolved the valve 30, which is held normally in an almost closed position, will be opened or closed to a greater or less extent by the governor 40 as the speed of the shaft is greater or less. This affords a constant pressure and supply of the fluid to be atomized and prevents the over-supply and consequent improper nebulization of the fluid when the speed of the machine is for any reason reduced, withou cutting off the fluid supply. 7

The operation of our device, as is evident from the above description, is simple and effective. Power, suitabl applied to pulleys 20 and 21 will revolve fans 15 and 19, and also shaft 9. As said shaft 9 is revolved, the governor regulates the supply of fluid to the housing 27, and consequently to the fans through the channel 34. The fans, as before stated may be revolved in diflerent directions and at various speeds, to regulate the currents and distribution of atomized fluid.

It is obvious that the details of this device as above set forth are only one embodiment of our device, and that the construction may be varied or changed as found desirable while still remaining within the scope of the appended claims.

Having thus described our invention, what we claim as new and desire to secure by Letters Patent is 1. An atomizer comprising in combination, a pair of spaced concentric cooperating disks, arranged in juxtaposition to each other, means for introducing liquid at the centers of said disks into the space between the same, and means for revolving said disks to distribute the liquid centrifugally.

An atomizer comprising, in combination, a pair of spaced concentric cooperating disks arranged in juxtaposition to. each other, means for introducing liquid at the centers of said disks into the space between the same, means for regulating the supply of liquid, and means for revolving said disks to distribute the liquid centrifugally.
